How do the electrons behave in the planetary model, that was initially supported by Bohr

c is the answer because when something is left after something evaporates that shows the chemical change.

explanation:

2b2t

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
